Abstract
A method of controlling power of a user equipment for device to device communication in a wireless communication system, and a user equipment thereof, are provided. The method includes receiving power control related information of the D2D communication from a Base Station (BS), determining transmission power of the UE based on maximum available power of the UE and the received power control related information of the D2D communication, and transmitting data according to the determined transmission power.
Claims22
A method of controlling power of a User Equipment (UE) for Device to Device (D2D) communication in a wireless communication system, the method comprising:
- receiving power control related information of the D2D communication from a Base Station (BS);
- determining transmission power of the UE based on maximum available power of the UE and the received power control related information of the D2D communication;
- and
- transmitting data according to the determined transmission power.
A User Equipment (UE) controlling power for Device to Device (D2D) communication in a wireless communication system, the UE comprising:
- a transceiver for transmitting/receiving a signal to/from the UE or a Base Station (BS);
- and
- a controller for controlling to receive power control related information of the D2D communication from the BS, determine transmission power of the UE based on maximum available power of the UE and the received power control related information for the D2D communication, and transmit data according to the determined transmission power.
A method of controlling power of a User Equipment (UE) for Device to Device (D2D) communication in a wireless communication system, the method comprising:
- receiving transmission related information of the D2D communication from a Base Station (BS);
- determining whether a transmission subframe of cellular information to be transmitted to the BS is a subframe allowing the D2D communication based on the transmission related information;
- determining transmission power by using a first offset value included in the transmission related information when the transmission subframe is the subframe allowing the D2D communication as a result of the determination;
- and
- transmitting the cellular information to the BS according to the determined transmission power.
A User Equipment (UE) controlling power for D2D communication in a wireless communication system, the UE comprising:
- a transceiver for transmitting/receiving a signal to/from the UE or a Base Station (BS);
- and
- a controller for controlling to receive transmission related information of the D2D communication from the BS, determine whether a transmission subframe of cellular information to be transmitted to the BS is a subframe allowing the D2D communication based on the transmission related information, determine transmission power by using a first offset value included in the transmission related information when the transmission subframe is the subframe allowing the D2D communication as a result of the determination, and transmit the cellular information to the BS according to the determined transmission power.
A method of performing multiplexing of a User Equipment (UE) for Device to Device (D2D) communication in a wireless communication system, the method comprising:
- determining whether transmission of uplink control information including ACK or NACK indicating forward information reception or forward information non-reception is required at a predetermined time point;
- determining whether information included in the uplink control information is ACK or NACK when the transmission is required;
- and
- transmitting the uplink control information to a Base Station (BS) without transmitting information of the D2D communication when the information included in the uplink control information is ACK as a result of the determination.
A User Equipment (UE) multiplexing cellular information and Device to Device (D2D) communication information in a wireless communication system, the UE comprising:
- a transceiver for transmitting/receiving a signal to/from the UE or a Base Station (BS);
- and
- a controller for controlling to determine whether transmission of uplink control information including ACK or NACK indicating forward information reception or forward information non-reception is required at a predetermined time point, determine whether information included in the uplink control information is ACK or NACK when the transmission is required, and transmit the uplink control information to the base station without transmitting information of the D2D communication when the information included in the uplink control information is ACK as a result of the determination.
